Under the heading "Disputed", the quote "Power ought to serve as a check to power" as quoted in Hostile Takeover (2004) by S. Andrew Swann, is said to not have been located in Montesquieu's works, although a reference to De l'Esprit des Lois Book V Chapter 14 is given, which alludes to a similar concept in completely different words. However, earlier on the same page, the quote from Swann is reported almost exactly to have been given in De l'Esprit des Lois Book XI Chapter 4: "[To prevent this abuse, it is necessary from the very nature of things that] power should be a check to power."

Therefore, it is an error for this quote to be disputed; the correct source is known. 73.53.61.168 14:15, 19 July 2014 (UTC)
